Affordable and well made, Cambridge Audio's intergrated amplifiers fill a gap between the one box system and full separates.

Adding to the audiophile specifications are separate transformer taps for left & right channels, twin rectifiers and separate PSUs for dual-mono operation of the left and right power amplifiers. Meanwhile a high grade film type volume pot means the 651A also performs as well at low levels as at higher volumes.

Whatever hi-fi speaker you choose, the 651A is designed to drive almost any model with ease. Our retuned output stage featuring Sanken output transistors gives excellent bass response and dynamic control.

We all like to crank up the volume from time to time and their proprietary CAP5 system ensures unrivalled peace of mind against overloads, faults and clipping.

Meanwhile, connection support for analogue sources like CD players, iPod docks and tuners is better than ever so whether you store or stream music from your computer, iPhone or maybe you prefer the luscious sound of good old vinyl, the all new Cambridge Audio 651 will make all your music sound amazing.

Class-leading power of 75 Watts per channel remains another massive advantage and a whole host of custom designed components together with their legendary approach to design means whatever you're listening to, it'll simply sound fantastic.  


AZUR 351A Intergrated


The 351A offers a wide range of inputs so you can connect and enhance all your entertainment devices. Most importantly, we've developed a brand new USB audio input so you can directly connect your Mac or PC. Best of all, this USB connection is mated to an onboard Burr Brown DAC (Digital to Analogue Converter) which automatically pulls a digital audio signal from your computer, bypassing its basic soundcard and taking care of the delicate digital to analogue conversion process inside the amplifier. So for the growing fans of iTunes and streaming services like Spotify, you can connect your computer to the 351A and use it as your primary audio source with CD quality results!

iPods and MP3 players also get the VIP treatment and can be connected directly to the front panel via a dedicated 3.5mm jack. In addition, our supplied remote features iPod command codes enabling control your iPad, iPhone or iPod when connected to a suitable dock such as those from Cambridge Audio.

Finally, a raft of gold plated audio connections are available for all your other entertainment sources like CD players, tuners, network players and even your TV

At 45 watts a channel the 351A delivers clean sound from a small box.
